Quidway S6500 Series Ethernet Switches
It is better to configure the BPDU protection on the edged port, so as to prevent the
switch from being attacked.
Before BPDU protection is enabled on the switch, the port runs as a non-edge port
when it receives BPDU, even if the user has set it as an edge port.
By default, all the Ethernet ports of the switch have been configured as non-edge ports.
Note:
It is better to configure the port directly connected with terminal as the edged port, and
enable the BPDU function on the port. That is to realize fast state-transition and prevent
the switch from being attacked.

1.2.11 Configure the Path Cost of a Port

Path Cost is related to the speed of the link connected to the port. On the MSTP switch,
a port can be configured with different path costs for different STIs. Thus the traffic from
different VLANs can run over different physical links, thereby implementing the
VLAN-based load-balancing.
You can configure the path cost of a port in the following ways.
I. Configure in system view
Perform the following configuration in system view.
